➡️ Let’s get started

sudo systemctl start symphonyd && sudo journalctl -u symphonyd -f -o cat

➡️ Log Command

journalctl -u symphonyd -f -o cat

➡️ Create wallet

symphonyd keys add wallet-name

➡️ Import wallet

symphonyd keys add wallet-name --recover

➡️ Faucet

Faucet

➡️ Create Validator

symphonyd tendermint show-validator

rm -rf /root/validator.json

nano /root/validator.json

➡️ Complete deletion

cd $HOME
sudo systemctl stop symphonyd
sudo systemctl disable symphonyd
sudo rm -rf /etc/systemd/system/symphonyd.service
sudo systemctl daemon-reload
sudo rm -f /usr/local/bin/symphonyd
sudo rm -f $(which symphonyd)

➡️ Block check

local_height=$(curl -s localhost:${SYMPHONY_PORT}657/status | jq -r .result.sync_info.latest_block_height); network_height=$(curl -s https://symphony-testnet-rpc.mictonode.com/status | jq -r .result.sync_info.latest_block_height); blocks_left=$((network_height - local_height)); echo "Your node height: $local_height"; echo "Network height: $network_height"; echo "Blocks left: $blocks_left"

• Your node height - the current block of your node
• Network height - the last block of the network
• Blocks left - how many blocks your node has left to sync.
